1 To all zrhom it may concern:

tion.

Be'it known that I, THOMAS F. CASEY, a citizen of the United States, and a resident of the city-of'New York, borough of Manhattan, in the county andState of New York, have invented a new and Improved Control Apparatus-for Fuel-Supply for Internal-Combustion Engines, of which the following is a full, clear, and exact descrip- Among the principal objects which the present invention has in view are: to prevent an unauthorized supply of fuel to an internal combustion engine; to provide a combination lock for controlling the flow of fuel to an internal combustion engine; to provide an audible alarm actuated by said lock.

, when, tampered with; and to provide a polymembered means for determining the supply of explosive fuel to internal combustion engines, said members beingdisguised in arrangement.

Drawings.--Figure 1 is an assembly of a g'asolene tank, carbureter and. manifold therefor; agas supply pipe connecting'said gasolene tank andQcarbureter, and an apparatus for controlling the flow through said I pipe, said apparatus being constructed and arranged in accordance with the present invention- Fi 2 is an assembl showin contact ends of the members of said apparatus when arranged in correspondence with the positien shown in Fig. l of the drawings, an audible alarm, an electric source operat- .ing the same, and a controlling switch therefor; Fig.3 is a. top plan view of the controlling apparatus herein described, partly in section'to show the free-way channel with g which the apparatus is provided and the conploying an apparatus constructed in accordance with the present invention, and the ends of said sections are connected to the apparatus by unions 12. As seen best in Fig. 3 of the drawings, the apparatus has a solid bar-like body portion 13, through which a channel 14: is formed. Intersecting the channel 11 are a series of bores, each pro- Specification of -I .etter's Patent.

vided to receive a plug valve 15. The valves 15 have each a passage formed therein for registry with the channel 14. Each valve 15 has a key extension 16, and each extension 16 has a wrench head 17. The head 17 is preferably shaped to form a square ahutment 18 and a flat surface adjoining the same.

The shape of the key .heads maybe varied. It is preferred, however, that the shape with whiclrthey are supplied, should be such as to indlcate or suggest a straight line or normal relation. In the normal position, or what might be termed, the suggested normal position of the valves 15, the heads 17 would be so turned'that the flat surfaces thereof would be in line, as are the heads in the valves at stations numbered 1, 3, 5 and 7 in Fig. 3. When the valves at stations numbered 2, l and 6v are turned so that their heads coincide with the heads of the other valves, it will be seen that the ports in the said valves 2, 4 and 6 are perpendicular to the. channel 14, and block the same.

The owner employing this apparatus to safeguard his machine, knows the combination, and when he leaves the machine he turns the valves at the stations 2, 4 and 6, if such is the combination, so that the heads are alined. If a meddler or thief desires to operate the machine, it is necessary for him to turn one of the plugs located at the seven stations, and not knowing the combination, he is liable to turn one of the plugs at the stations 1, 3, 5 and 7, which would turn the ports in those valves crosswise of the channel 14, and so block the flow of gas through the pipe 9.

It will be understood that the valves 15 may be variously arranged, and the combinations may be altered, so that rarely, if ever, two machlneswould have the same arrangement or combination.

Themachine which is equipped with the herein-described apparatus, isilikwise furnished with aswitch 23 secretly disposed.

In the normal operation of the apparatus, the owner on leaving the machine, closes the switch. Thereafter, if the valves at the stations 2, 4 and 6 be-turned, which would open communication through the sections of the pipe 9, the contacts 21 would wipe on the bars 22 and complete the electrio circuit incorporating the wire 24, bell 19, battery 20 and common return wire 25.

If the thief should not know the combination and should turn an one of the valves 15 at the stations 1, 8, 5 and 7, the electric contacts 21 connected therewith would complete the electric circuit through the wire 24, switch 23, bell 19, and battery 20, or, if turned in the posite direction, through the .bar 26, wire bell 19, battery 20, and common return wire 25. in, should the owner of the machine be careless and leave the machine with the switch 23 dis ino nv 'tion,asseenbestin Fig. 2 of the rawmgs, the thief runs a further chance of turning the valves 15 at the stations 2, 4 and 6, in the wrong direction when the contacts 21 thereof would engage the bar 26. The bar 26 and wire 27 connected therewith are-at all times in what anay be termed a closed circuit condition ready to operate the alarm bell 19.

Claims: 1. An ap aratus as characterized comprising an e ongated channel member; a series of plugz-idisposed transverse the channel 5 of said member, each of said plugs having a port therein adapted for registry with sai channel, and each of said rts being provided with a wrench .head havi an exposed surface indicative of a norma orderly arrangement with reference to the heads of the ot er plugs, the heads in certain of said plugs having a special arran ment diil'ermg from the arra ment 0 the heads'of the other plugs wit reference to the ports therein; and an electric alarm system embodying an electric current supply, an audi ble alarm, and contacts for engaging said plugs when moved from the service position thereof. 4

2. Anapparatus as characterized omprisin .an elongated channel member; a serice 0 plugs disposed transverse the channel of said member, each of said plugs having a part therein ada ted for registry with and c nnel, and eac of said ports being provided with a wrench head having an exposed surface indicative of a normal orderly arran ment with reference to the heads of the ot er plugs, the heads in certain of said plugs having a special arran ment difi'er- 1 from the arrangement 0 the heads of ot er plugs with reference to the rts therein; an electric alarm system em ying an electric current supply; an audible alarm, and contacts for engaging said plugs when moved from the service position thereof; and a manually-controlled switch for said circuit operable for completing the circuit when the plugs are in service relation.

3. An apparatus as characterized comprising a body portion forming part ,of the gas supply pipe a plurality of rotary valves operatively mounted on said body portion for closing the passage therethrough; a plurality of laterally extended electrical contacts, one mounted on the stem of each of said valves; a plurality of contact bars disposed at opposite sides of said body e(portion to engage said contacts when turn to the active position thereof; and an audible alarm incorporated in the electric circuit of which said bars, contacts and body portion form a part.

In testimony whereof I have signed my name to this specification in the presence of two submribing witnesses.
